Graviola, also known as Annona muricata, is a tropical fruit-bearing tree native to the Americas. Graviola (Annona muricata; soursop) contains annonaceous acetogenins (e.g., annonacin, bullatacin-class compounds) that are widely described as mitochondrial complex I inhibitors, producing ATP depletion and downstream stress signaling that can lead to cell-cycle arrest and apoptosis in many in-vitro cancer models. A key real-world constraint is safety: epidemiology in the French Caribbean reports an association between high Annonaceae consumption and atypical parkinsonism, and animal data indicate annonacin can enter brain tissue and drive ATP depletion with neurodegenerative patterns under chronic exposure; therefore Graviola products should be treated as higher-risk than many polyphenols and should not be framed as a casual long-term supplement. GLUT1 inhibitor? The major pathways involved in Graviola's anti-cancer effects include: -Reported reduction of glucose uptake (e.g., GLUT1 expression) in selected tumor models.: Graviola extracts have been shown to inhibit the activity of lactate dehydrogenase (LDH), a key enzyme involved in glycolysis, the process by which cancer cells produce energy. By inhibiting LDH, Graviola reduces the production of lactate, a key metabolite that fuels cancer cell growth.(likely secondary to mitochondrial ATP depletion) -Inhibition of glucose uptake: Graviola extracts have also been shown to inhibit the uptake of glucose by cancer cells, further reducing their energy production. -Inhibition of the PI3K/AKT pathway: The PI3K/AKT pathway is a key signaling pathway involved in cell survival and proliferation. Graviola extracts have been shown to inhibit this pathway, leading to reduced cancer cell growth and survival. -Induction of apoptosis: Graviola extracts have been shown to induce apoptosis in cancer cells by activating pro-apoptotic proteins and inhibiting anti-apoptotic proteins. The major compounds responsible for Graviola's anti-cancer effects are: Annonaceous acetogenins: These are a group of compounds found in Graviola that have been shown to inhibit cancer cell growth and induce apoptosis.

| Also known as CP32. Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death. As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression. Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy. Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent. On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer. Procaspase-3 is a apoptotic marker protein. Prognostic significance: • High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers. • Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers. |
